This DuoSet ELISA Development kit contains the basic components required for the development of sandwich ELISAs to measure natural and Recombinant human S100 Calcium Binding Protein A8/S100 Calcium Binding Protein A9 (S100A8/S100A9 Heterodimer). The suggested diluent is suitable for the analysis of most cell culture supernate, serum, plasma, saliva, human milk, urine, and fecal samples. Diluents for complex matrices, such as serum, plasma, saliva, human milk, urine, and feces, should be evaluated prior to use in this DuoSet.

Background: S100A8/S100A9 Heterodimer
S100A8 (also MRP8 and calgranulin A) is a 10 kDa member of the S100 family, EF-hand superfamily of Ca-binding proteins. It is produced by neutrophils and monocytes, and forms Ca 2+-dependent heterodimer/heterotetramer complexes (termed calprotectin) with S100A9. It functions both intracellularly and extracellularly, where it binds to RAGE and CD36. Human S100A8 is 93 amino acids (aa) in length. It contains two EF-hand motifs (aa 12 - 47 and 46 - 81) and one high-affinity Ca 2+-binding site (aa 59 - 70). There may be one splice form that shows a 15 aa substitution for the C-terminal 14 amino acids. Although mouse S100A8 is cleaved by MMP-2 after Asn21, it is unclear if human S100A8 is susceptible. Full-length human S100A8 is 57% and 74% aa identical to mouse and canine S100A8, respectively.
